FLUID SEAL.

Specification of Letters Patent.

Patented June 1 3 1916.

Y Application filed June 30, 1915. Serial No. 37,245.

Be it known that I, JULIUs WITH,

a citizenof the United States, residing at .7

Port Townsend, in the county of J efl'erson and State of Washington, have invented a new and useful Fluid Seal; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

ThlS invention relates to an improved fluid seal for garbage can closures, for exeluding insects and the like, and preventing the odor from escaping.

One of the objects of the invention is to provide a fluid seal of this nature comprlsing an annular channel on the upper perlpheral edge of the receptacle, or formed from an extension flange of the upper portion of a receptacle, to receive an annular tongue or flange of the closure for the receptacle, the annular channel being designed to receive water, oil, or any other fluid, whereby a liquid seal may be maintained between the closure and the receptacle.

A further object of the invention is to provide the annular flange or tongue at its lower portion with a T-shaped part (which is annular) partially curved in cross section,

to fit the curvature of the bottom of the annular channel, and owing to the liquid or fluid in the channel, the closure is not only sealed, but the T-shaped part curved in cross section tends to adhere to the curved bottom of the channel, thereby rendering the cover somewhat diflicult to be removed.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a vertical sectional view through a garbage can, showing the sealing connection between the closure and the can. Fig. 2 is a plan view, showing the closure broken away, and parts in section, illustrating the annular channel, and the annular flange, and which view is taken upon line 22 of Fig. 1. Fig. 3 is a .vertical sectional view through-a garbage can and closure therefor, illustrating another form of sealing connection. Fig. 4 is a view taken upon line 4-4 of Fig. 3, showing the closure in elevation partly broken away, and

illustrating the annular channel and the annular flange in section.

Referring more especially to the drawings,

1 designates a garbage can, which may be any suitable shape or configuration, and is provided with a bottom 2 riveted orotherwise secured at 3 to the lower edge of the cylindrical wall of the can. The upper part a of the wall of the can is bent upon itself at 4,

extending downwardly at 5 and being semicircular curved in cross section as shown at 6, and then curved upwardly at 7, thereby forming an annular channel8. The upper edge portion of the outer wall 7 of the chanagainst the under surface of the closure for i a short distance shown at 12, and this bent portion 13 is bent again asat 14 to form the downwardly extending flange 15, which enters the U-shaped channel 8. The lower part i of the flange 15 is T-shaped as at 16, which is curved in cross section as shown, and? which is adapted to adhere to the curved part 6 of the U-shaped channel 8, owing to themoisture from the sealing fluid 17 which prevents the escape of the odor from the garbage can, and excludes the insects and the like. The closure 10 is provided with a suitable handle 18.

In Fig. 4, instead of forming the channel member 8 integral with the can, it is riveted to the can as shown at 8 Also the flange 15 (which is annular in plan view, and angular in cross section) is riveted at 15 to the closure 10 instead of being made integral with the closure. The T-shaped portion 16 is omitted, and the lower edge 15 of the flange 15* adheres to the curved bottom of the channel, owing to the moisture from the sealing fluid. The closure 10 in Figs. 3 and 4 is also provided with a handle 18.

It is to be noted that the T-shaped part 16 is not quite as wid as the width of the channel, so that the T-shaped part will easily enter the channel, and will not displace the liquid. It will also be noticed that the outer portion of the closure overlies and extends downwardly over the. outer wall 7 of the channel.

The invention having been set forth, what annular channel member U-shaped in cross section carried by the can adjacent its upper edge, a closure having an annular flange ofi'- set inwardly from the outer edge of the clo sure and extending downwardly and into the U-shaped channel, said annular flange having a T-shaped part at its lower portion curved in cross section to correspondingly lit the lower curvature of the bottom of the U-shaped channel member and having a liquid seal which causes the T-shaped part curved in cross section to adhere to the curvature of the bottom of the channel member, the outer edge portion of the closure extending downwardly and overlying the outer 1 JULIUS E.
